Finish existing subtitle files in batches while keeping source files on your device. ClipCaption adjusts timing, wraps text and flags captions that deserve a manual review.
What You Receive
- A complete offline HTML application.
- SRT and basic VTT input support.
- Positive or negative timing offsets in seconds.
- Configurable 16–80 character line wrapping.
- Optional removal of formatting tags.
- Review flags for overlaps, long words, more than two lines and reading speed above 22 characters per second.
- SRT and VTT exports plus a CSV review report in one ZIP.
- Setup instructions and a use license.
How It Works
Extract the ZIP, open index.html, choose your subtitle files and set the offset and line width. Export and review the report. Supports up to 20 files per batch, 10 MB per input and 50,000 cues per file.
Timing And Formatting
Overlaps are flagged, not silently removed. If a negative offset removes a caption before time zero, processing stops with an explanation. Styled, regional and positioned VTT files are rejected to avoid silently losing those features; export basic VTT first.
Privacy And Compatibility
Processing happens on your device. Real SRT import, timing shift and SRT/VTT/CSV exports were tested in Microsoft Edge on Windows. No account, subscription or external service is required.
Scope
This product formats existing captions. It does not transcribe audio, translate speech, embed captions into video or guarantee broadcast compliance.
License
Use for your own business or client work on your own devices. Generated subtitle files and reports may be shared with clients. Do not resell or redistribute the application.
A one-time purchase of version 1.0.
